<p>A patterned high density magnetic recording medium which is characterized in that the arrangement of recessed trenches are formed in a matrix thin film covering a medium substrate or in the medium substrate by etching, and the recessed in the trench arrangement are filled with a magnetic material up to the height of the matrix thin film surface or the medium substrate surface to form the arrangement of magnetic bits; and a streamlined manufacturing process of the patterned medium which is excellent in productivity, has a streamlined construction and has little environmental load.</p> |
